BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

CiteSpace software was used for visual analysis.Results:A total of 630 articles were included, and the number of publications was on the rise. The country with the highest number of publications was the United States, with 8 out of the top 10 institutions in terms of publication volume coming from the United States. The author with the highest number of publications was Grudzen. The top 10 journals in terms of citation frequency were mostly specialized journals on palliative care and first aid. The results of keyword analysis showed that a total of 15 clustering labels and 20 emergent words were output, reflecting the changes of key research objects, main research types and areas of concern.Conclusions:At present, nursing research in this field is in the development stage in China. We can draw on the practical experience of foreign countries to further explore the emergency palliative care model and service system based on China's national conditions.

Objective:To explore the application of 4C teaching combined with case simulation teaching in the practice teaching of respiratory and critical care medicine nursing students.Methods:Eighty nursing practice students from 2019 to 2021 in the Department of Respiratory and Critical Care Medicine of Beijing Chaoyang Hospital Affiliated to Capital Medical University were selected as the research objects, and they were randomized into control group ( n=40) and observation group ( n=40). The control group adopted traditional teaching, and the observation group adopted 4C teaching combined with case simulation teaching. The nursing comprehensive ability and self-directed learning ability of the two groups of nursing students were compared, and the evaluation of teaching methods between the two groups was assessed. SPSS 22.0 was used for Chi-square test and t-test. Results:The scores of theoretical knowledge, ward management, prevention and control of hospital infection, basic nursing, standardized writing of nursing documents, and critical care of nursing students in the observation group were higher than those in the control group ( P<0.05); the scores and total scores of learning awareness, learning behavior, learning strategies, interpersonal relationships, and learning evaluation in the observation group were higher than those in the control group ( P<0.05). The observation group believed that their teaching method was better than the control group in terms of mobilizing learning initiative, improving basic nursing practices, promoting clinical communication skills, improving the ability to analyze and solve problems, enhancing the concept of humanistic care, helping to understand and master knowledge, and improving the overall quality ( P<0.05). Conclusion:The 4C teaching combined with case simulation teaching can improve the comprehensive nursing ability and self-directed learning ability of nursing students in department of respiratory and critical care medicine, and the nursing students have a high opinion of the teaching method.

Objective: To analyze the improvement of executive function in children with attention deficit hyperactivity disorder (ADHD) aged 7-14 years with comprehensive intervention and drug therapy alone, to provide a basis for intervention research to improve ADHD. Methods: A total of 80 children with ADHD treated in the Third People s Hospital of Ganzhou from January 2021 to June 2022 were randomly divided into intervention group and control group. The intervention group received drug and comprehensive intervention therapy, and sensory integration training once a week for 60 to 90 min each for 12 weeks, and conduct related training for caregivers and school teachers, the control group received only drug therapy. The changes of executive function were assessed by the stroop color word association test and the Wisconsin Card Sorting Test (WCST) after 12 weeks of intervention. Results: After intervention, the results of the Stroop color word test in the intervention group (3.25±0.98, 4.92±1.40, 10.17±1.28) showed statistically significant differences ( t=12.94, 15.36, 26.34 , P <0.01) compared with those before intervention (6.47±1.92, 8.35±1.25, 16.55±1.57). There were also statistically significant differences ( t=6.76, 15.01, 16.15, P <0.01) in the control group ( 3.95 ±1.01, 5.45±1.15, 12.35±0.86) compared to those before intervention (6.17±1.87, 8.10±1.03, 16.02±1.38). Before intervention, the number of perseverative errors, non perseverative errors, and completed categories by WCST in the intervention group were (47.77±4.50, 35.50±2.37, 3.97±1.07), and in the control group were (46.45±7.34, 34.87±2.29, 3.70±1.11). After intervention, those of the intervention group and control group were (31.42±2.01, 24.75±2.05, 5.05±1.13) and (32.82±2.57, 25.55±1.04, 4.25±1.48), respectively. There were significant differences in the two groups before and after intervention ( t =21.93, 22.27 , -10.37; 10.84, 26.81, -6.90, P <0.01). After intervention, there were significant differences in the number of Stroop color word test errors, perseverative errors and non perseverative errors in WCST between the two groups ( t=-2.94, 2.29, -9.07, -2.35 , -2.06, P <0.05). Conclusion Through training for children and the therapy model of comprehensive intervention could significantly improve the executive function of children for a certain extent.

Objective:To evaluate the safety and efficacy of combination of submucosal tunneling endoscopic septum division (STESD) and peroral endoscopic myotomy (POEM) for the treatment of esophageal epiphrenic diverticulum with esophagogastric junction (EGJ) outflow tract disorder.Methods:From October 2017 to August 2021, 6 patients with esophageal epiphrenic diverticulum complicated with EGJ outflow tract disorder receiving combination of STESD and POEM in the Endoscopic Center of the First Affiliated Hospital of Nanjing Medical University were enrolled. The clinical characteristics of the patients were retrospectively analyzed, which included the ratio of male to female, age, course of disease, length of diverticula, location, whether with multiple diverticula, type of EGJ outflow tract disorders, whether the endoscopic technique was successful (the completion of all steps under endoscopy, including tunnel establishment and diverticulum cristae, lower esophageal sphincter and cardia muscularis propria incision); operation time, changes in the severity of clinical symptoms before and after operation (including weight loss, dysphagia, retrosternal pain, and reflux assessed using the Eckardt score), intraoperative and postoperative complications, and follow-up, including whether achieved clinical success (complete or nearly complete improvement of dysphagia, vomiting after eating, retrosternal pain, regurgitation, weight loss, no need for repeat endoscopic intervention during follow-up) and adverse events. Descriptive methods were used for statistical analysis.Results:The male to female ratio of the 6 patients was 3 to 3, the median age was 69.2 years old, and the median disease course was 92.3 months. The median length of the diverticula was 47.5 mm. Diverticulum was located in the right wall of esophagus in 4 cases and in the left wall of esophagus in 2 cases, of which 1 patient was multiple diverticulum of esophagus. Achalasia was found in 5 cases, and EGJ outflow obstruction was found in 1 case. All the 6 patients successfully completed combination of STESD and POEM, and all achieved successful edoscopic technique. The operation time (range) was 55 min (40 to 70 min). Clinical symptom Eckardt score (range) before and after operation was 9.0 (7.0 to 11.0) and 1.3 (1.0 to 2.0), respectively. After operation the clinical symptom improved compared with that before operation. There were no delayed bleeding, perforation, infection, subcutaneous emphysema and other complications and severe adverse events. Six patients were all cured and discharged. Follow-up period was 1 to 50 months. The symptoms of dysphagia, vomiting after eating, retrosternal pain, regurgitation and weight loss were all significantly improved compared with those before operation. There were no severe adverse events and all achieved clinical success.Conclusions:Combination of STESD and POEM is safe and effective in the treatment of esophageal epiphrenic diverticulum with EGJ outflow tract disorder, and has good short-term and long-term effects.

Objective To investigate the differential MSCT diagnostic features and comparative study of subtypes of renal cell carcinoma (RCC). Methods All of the renal cell carcinomas including 14 chromophobe RCCs (ChRCC), 10 papillary RCCs type 1(PRCC Ⅰ), 15 papillary RCCs type 2 (PRCC Ⅱ), 7 mucinous tubular and spindle cell carcinomas (MTSCCs) were investigated except for clear cell RCC. Dynamic contrast-enhanced CT was conducted in each case after intravenous administration of contrast agent, and the data including all the CT manifestations and the enhancement features were analyzed and contrasted together. Results The indexes including enhancement homogeneity, border of the tumor, renal pelvis violation, blood vessel in tumor showed statistically significant difference between the 4 subtypes (P<0.05), but no difference in the calcification of the tumor. Only the enhancement degree of MTSCC was lower than the kidney medulla in all of the three enhancement scanning phases, while the other 3 tumors' enhancement degree was higher than the kidney medulla in the cortical phase. Peak contrast enhancement of ChRCC was located in the cortical phase, however, peak contrast enhancement of the others did in the nephrographic phase. Conclusions Enhancement characteristics combined CT features is of great help in differential diagnosis of 4 subtypes of RCC.

Objective To investigate the clinical risk factors of delayed cerebral ischemia (DCI) in patients with aneurysmal subarachnoid hemorrhage (aSAH).Methods From January 2015 to April 2016,106 consecutive patients with aSAH treated with endovascular embolization at the Department of Neurosurgery,Nanjing General Hospital of Nanjing Military Command were enrolled retrospectively.The patients were divided into either a DCI group (n =34) or a non-DCI group (n =72) according to whether the occurrence of DCI.The general information of patients were collected,including sex,age,Hunt-Hess grade,modified Fisher grade,world federation of neurosurgical societies (WFNS) grade,acute cerebral edema,early (bleeding 1-3 d) hypoalbuminemia,and hypohemoglobinemia.Univariate and multivariate Logistic regression analyses were used to analyze the risk factors for occurrence of DCI.Results The incidence of DCI was 32.1％ (34/106).The Hunt-Hess grade ≥ Ⅲ,modified Fisher grade ≥ Ⅲ,WFNS grade ≥ Ⅳ,acute cerebral edema,the incidences of hypoalbuminemia and hypohemoglobinemia in the DCI group were higher than those in the non-DCI group.There were significant differences between the 2 groups (all P ＜ 0.05).There were no significant differences in the ratios of sex,age ≥ 55 years,hypertension,diabetes and hyponatremia between the 2 groups (all P ＞ 0.05).In univariate analysis,the Hunt-Hess grade ≥ Ⅲ grade,modified Fisher grade ≥ Ⅲ,WFNS grade ≥ Ⅳ on admission,and hypoalbuminemia were used as the independent variables for multivariate analysis,the results showed that WFNS grade ≥ Ⅳ (OR,8.02;95 ％ CI 2.41-26.70),modified Fisher grades ≥ Ⅲ (OR,4.44;95％ CI 1.38-14.32),and hypoalbuminemia at day 1-3 (OR,5.42;95％ CI 1.40-20.76) were the independent risk factors for occurring DCI in patients with aSAH (all P ＜ 0.05),and the Hunt-Hess grade ≥ Ⅲ was not the risk factor for occurring DCI in patients with aSAH (OR,1.86;95％ CI 0.39-8.88,P ＞ 0.05).Conclusion The patients with hypoalbuminemia,WFNS grade≥Ⅳ on adrnission,and modified Fisher grade ≥ Ⅲ may were the independent risk factors DCI after aSAH,and the clinical diagnosis and treatment should attach great importance to.

Objective To investigate the current situation in Chinese rheumatologic physicians' clinical diagnosis and evaluation of Takayasu's arteritis (TA).Methods Nineteen rheumatology experts and three vascular surgery specialists in China were invited to make the nationwide investigation for the first time about the diagnosis and disease activity evaluation of TA in China,through the questionnaire survey on the internet.Weighted average was used to calculate the average scores of corresponding problems.Results Chinese experts mainly adopted 1990 American College of Rheumatology (ACR) classification criteria for clinical diagnosis of TA.In details,symptoms of age,limb claudication and amaurosis,signs including pulselessness or pulse weakening,vascular bruits,increasing bilateral pulse pressure and hypertension and acute phase reactants (APR) were critical to the clinical diagnosis of TA.Besides,noninvasive imaging examinations,such as computed tomography angiography (CTA),magnetic resonance angiography (MRA),vascular ultrasonography,and positron emission tomography (PET) were also of great importance.In the aspect of disease activity assessment,Chinese experts mainly used Kerr scoring tool.APR and noninvasive radiological examinations were considered with vital value.Some TA patients with carotid artery involvement were recommended using vascular ultrasonography,while others with pulmonary artery and thoracic/abdominal aorta trunk involvement were preferred CTA other than MRA.Conclusions APR and noninvasive imaging examinations were thought with great help to make clinical diagnosis and evaluation of TA for Chinese physicians.
